surface area= perimeter x height + 2b
s= pxh+2b
example: 18(8)+2(12)
explain: 18 is the perimeter and 8 is the height then you have to add the base times 2
3*3*3=9 perhaps?? And then it would be in Surface Area??
Answer:
The change in value is 19,000 altogether and 1900/year
Step-by-step explanation:
Change in value:
initial value - final value
= $26,000 - $7000
= $19,000
Change in value/year:
change in value/time
= $19,000/10
= $1900/year
Slope of the line is -1.
Step-by-step explanation:
Given points are,
(-5.5,6.1),(-2.5,3.1)
Here,

Slope = m = 
Putting values;

Slope of the line is -1.
